如何修复 Terraform 提供程序配置不存在

Question

使用 Terraform v1.2.5 我正在尝试部署 AWS VPC 对等方。 但是，以下代码验证失败：

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 4.1"
    }
  }
}

provider "aws" {
  region = "us-east-1"
}

data "aws_vpc" "accepter" {
    provider = aws.accepter
    id = "${var.accepter_vpc_id}"
}

locals {
    accepter_account_id = "${element(split(":", data.aws_vpc.accepter.arn), 4)}"
}

resource "aws_vpc_peering_connection" "requester" {
  description   = "peer_to_${var.accepter_profile}"
  vpc_id        = "{$var.requester_vpc_id}"
  peer_vpc_id   = "${data.aws_vpc.accepter.id}"
  peer_owner_id = "${local.accepter_account_id}"
}

验证此 terraform 代码时，我收到以下错误：

$ terraform validate
╷
│ Error: Provider configuration not present
│
│ To work with data.aws_vpc.accepter its original provider configuration at provider["registry.terraform.io/hashicorp/aws"].accepter is
│ required, but it has been removed. This occurs when a provider configuration is removed while objects created by that provider still exist
│ in the state. Re-add the provider configuration to destroy data.aws_vpc.accepter, after which you can remove the provider configuration
│ again.

我缺少或配置错误导致此错误的原因是什么？

Answer 1

您需要提供您在此处引用的别名提供程序版本：

data "aws_vpc" "accepter" {
    provider = aws.accepter # <--- missing aliased provider
    id = var.accepter_vpc_id
}

要解决此问题，您只需添加相应的别名提供程序块 [1]：

provider "aws" {
  alias  = "accepter"
  region = "us-east-1" # make sure the region is right
}

Answer 2

由于 VPC 对等互连是“区域间”对等互连，因此我们需要 2 个 AWS 区域。 因此，实现这一点的方法是创建 AWS 提供商和 AWS 别名提供商块。

看一个例子：

 provider "aws" { region = "us-east-1" # Requester's credentials. } provider "aws" { alias = "peer" region = "us-west-2" # Accepter's credentials. }

Answer 3

您的资源不知道要使用哪个提供程序，您提供的那个不存在。

你有两个选择：

1. 为提供商添加别名：

provider "aws" {
  region = "us-east-1"
  alias = "accepter"
}

2. 从data "aws_vpc" "accepter"中删除行provider = aws.accepter

我想，不知何故，第一个对你来说更有效。
